Delaware Filed Sept. 13, 1958, Ser. No. 761,821 Claims priority, application Netherlands Sept. 20, 1957 3 Claims. (Cl. 30-43) This invention relates to dry-shavers comprising a hinged cutting plate.

The invention is characterized by an attachment of the hinge to the casing of the apparatus such that, in the open condition, the plate can be removed by hand Without the use of tools.

The invention aflords the advantage that the cutting plate can be exchanged in a simple manner for a cutting plate of another kind. Furthermore, if a plurality of cutting plates are united into one cutting head, complete cutting heads may be put on the market for replacement, which can be positioned on the apparatus in a simple manner by the user himself instead of a cutting head which no longer operates satisfactorily. It is also possible to exchange a cutting plate in such a cutting head in a simpler manner it the cutting head as a whole can be removed from the apparatus.

According to a further feature of the invention, the hinge is secured to the casing in a manner such that a hinge blade is located in a groove of the casing and arrested in the desired position by a spring located in the groove and engaging behind a protuberance of the hinge blade.

A cutting plate or a cutting head may thus be arranged on the apparatus in a very simple manner by sliding the hinge blade into the groove of the casing intended therefor. In the introduced position, the blade is arrested by a spring so that there is no risk of the hinge blade sliding out of the groove.

In order to avoid any play between the hinge blade and the groove, the hinge blade itself is made resilient.

The invention also relates to a separate cutting plate and a separating cutting head provided with a hinge blade according to the invention.

In order that the invention may be readily carried into efiect, it will now be described more fully, by way of example, with reference to the accompanying drawing, in which:

FIG. 1 is a bottom view of a separate cutting head according to the invention;

FIG. 2 is a cross-sectional view of the casing of the dry-shaver, to which the cutting head of FIG. 1 may be secured;

FIG. 3 is a plan view of the casing of the dry-shaver having a cut hinge blade located in the groove, and

FIG. 4 is a cross-sectional view of FIG. 3, taken along the line IV-IV, without a hinge blade.

The cutting head shown in FIG. 1 comprises a mount 1, in which two cutting plates 2 are arranged in the usual manner. Associated cutting members 3 are shown below the cutting plates 2. The mount 1, together with a hinge plate 4, constitutes a hinge. The hinge plate 4 is provided with flanges 8 and 9 on opposite sides thereof as seen in FIGS. 1 and 3. The mount 1 and the hinge plate 4 are secured together in the usual manner by means of a spindle 5. The spindle is surrounded by a spring 6 keeping the mount 1 and the hinge plate 4 in predetermined relative positions. The mount 1 also has a latch 7.

An upright Wall 11 of the casing of the dry-shaver, which encloses a hair chamber 12, is provided with two grooves 13 and 14. Intermediate these grooves is a third groove 15 containing a spring 16. The flanges 8 and 9 of the hinge plate 4 can he slid into the grooves 13 and 14 until the lower side of the plate 4 abuts the base 17 of the hair chamber. In this position, the spring 16 engages behind a protuberance 18 of the hinge plate 4, thus locking it. Since the hinge plate 4 is made resilient, any play between this plate and the grooves 13 and 14 is suppressed, so that the position of this blade with respect to the casing of the apparatus is completely determined. In the secured position of the hinge plate 4, the hair chamber 12 can be closed by the mount 1. In order to hold the mount 1 as a cover on the hair chamber 12, the wall 11 of the hair chamber has a second spring 21, behind which the latch 7 engages in the closed condition of the cutting head. For opening the cutting head, the spring 21 may be moved clear off the latch 7 by means of a push button 22, whereafter the spring 6 causes the cutting head as a cover of the hair chamber to be tilted open.

What is claimed is:

1. A dry shaver comprising a shaver casing, a mount, a cutting plate and an associated cutting member in said mount, a plate depending from said mount, means including a spring hinging said plate to said mount whereby said plate is biased to a certain position relative to said mount, spaced groove means on said shaver casing, and a spring located therebetween for removably receiving said plate, said spring engaging one of the surfaces of said plate and spaced flanges on said plate for insertion and removal in said corresponding spaced groove means.

2. A dry shaver as claimed in claim 1 wherein said plate is provided with a protuberance and said spring engages said plate behind said protuberance.

3. A dry shaver comprising a shaver casing, a mount, a cutting plate and an associated cutting member in said mount, a plate depending from said mount, means including a spring hinging said plate to said mount whereby said plate is biased to a certain position relative to said mount, groove means in said shaver casing, spaced flanges on said plate for the insertion and removal thereof in said corresponding groove means, and a spring having one end mounted on said casing and the free end engaging one of the surfaces of said plate when said flanges are located in said groove means.
